On CDH2, (Cloudera EC2) No valid local directories in property:
mapred.local.dir
Hello,
Not sure if i should post this here or on Cloudera's message board,
but here goes.
When I run EC2 using the latest CDH2 and Hadoop 0.20 (by settiing the
env variables are hadoop-ec2),
and launch a job
hadoop jar ...
I get the following error
10/02/19 17:04:55 WARN mapred.JobClient: Use GenericOptionsParser for
parsing the arguments. Applications should implement Tool for the
same.

but the value of mapred.local.dir is "/mnt/hadoop/mapred/local"
Any ideas?

Hello,
I fixed this by running more than >=2 slaves.
I was testing with 1 when this error occurred.

Hi Saptarshi,
Can you please ssh into the JobTracker node and check that this
directory is mounted, writable by the hadoop user, and not full?
